Spectral Theory of Sturm-Liouville Operators Approximation by Regular Problems, for the case where one end point is regular, but they can be extended to the general case, as well as to Dirac systems, to discrete operators, and (partially) to ordinary differential operators of arbitrary order.infarct 发表于 2025-3-27 03:49:04

,Sturm’s 1836 Oscillation Results Evolution of the Theory,who first put the proofs on a rigorous basis, and major tools of analysis where introduced by Picone, Prüfer, Morse, Reid, and others. Some basic oscillation and disconjugacy results are given for the second-order case. We show how the definitions of oscillation and disconjugacy have more than one i失望昨天 发表于 2025-3-27 21:17:29
Charles Sturm and the Development of Sturm-Liouville Theory in the Years 1900 to 1950, is concerned with the remarkable development in the theory of Sturm-Liouville boundary value problems, which took place during the years from 1900 to 1950..Whilst many mathematicians contributed to Sturm-Liouville theory in this period, this manuscript is concerned with the early work of Sturm andGENRE 发表于 2025-3-28 00:40:59

Asymptotic Methods in the Spectral Analysis of Sturm-Liouville Operators,esponding self-adjoint operators. In particular, we review the main features of the theory of subordinacy by considering two standard cases, the half-line operator on .([0, ∞)) and the full-line operator on .(ℝ). It is assumed that the coefficient function . is locally integrable, that 0 is a regula龙卷风 发表于 2025-3-28 08:34:41
